    New rims -- Metal stuck in brake pads

    Just got a new set of TB-14 rims and within a few days of use, my shimano 105 brake pads were mucked up with metal, including a 1-2 mm deep pit full of aluminum. Even the areas that werent pitted had aluminum dust all over them. before using them on the new rims, i sanded the brakes down with fine grit to a very smooth finish, so I was a bit surprised. from reading, it seems like this maybe is a common problem with shimano brake pads? They are also of unknown age (came with the 1988 bike, probably replaced since then but who knows).

    Anyway, they are like Amazon.com : Shimano BR-5700-L RC55C3 Cartridge Brake Shoe Set (Road) : Bike Brake Pad Inserts : Sports & Outdoors those ones except they dont have the second screw to replace the pad (i.e. the pad is one with the cartridge as far as I can tell). I was reading that kool stop salmon's dont seem to have the same metal consuming problem, but I'm having trouble finding ones that aren't just inserts for reusable cartridges.

    Sooo what I was wondering was

    1) is it a shimano problem, or maybe just old brakes? or could I get away with purchasing, say, this set: Amazon.com : Shimano BR-5700-L RC55C3 Cartridge Brake Shoe Set (Road) : Bike Brake Pad Inserts : Sports & Outdoors with the added bonus that I could use modern brake inserts afterward?

    2) if it is a shimano problem... does this kool stop for dura ace/ultegra include the cartridge? Amazon.com : Kool Stop Bicycle Brake Pads : Bike Brake Pad Inserts : Sports & Outdoors They only have a pic for the continental version so I'm not sure

    3) otherwise, is there a place to buy reasonable priced 105 (1050 era late 80s) compatible shoe holders so I could get some kool stop inserts?

    Thanks!

    Get the koolstop pads and holders. The compound doesn't damage rims like the harder shimano compound pads. The model is "dura 2". Those continental ones are for different brake types.

    In the kool stop amazon page there is an option for "dura-ace/ultegra" as well as the contintental pictured... just wondering if those are the inserts only or include the rest.

    would those fit a vintage bike with 105 brake calipers? seems like a damn good deal if they do -- includes a replacement set even!

    Those are the ones I currently have on my '90 Cannondale 3.0 with Shimano 600 brakes - in fact I just replaced the original set of pads with the included replacement set a couple days ago. I'd expect them to fit the 105 bikes equally well.

    Sweet.. ordered. Thanks! Really bummed about my rims... there's a big palpable scratch all the way around one side. Will this wear away in time?

    i doubt if it's the brake pads. some rims have machined braking surfaces (TB-14's do) that are known for shedding aluminum shards for the first hundred miles or so. the shards imbed themselves in whatever pad is on there and make a racket when braking. i just clean out the pads with a sharp tool when i get home and forget about it. IME, it soon stops.

    and yes, the scratch will wear away eventually, in fact the entire braking surface will wear away eventually and you'll have to buy a new rim.

    if you want to you might think about taking some 220 wet/dry (i use it wet) sandpaper to the braking surface to clean it up a bit, it might help, cosmetically speaking. i suppose it could even reduce whatever shedding the rim has left to do.

    I love Shimano, but their brake pads are the problem. They eat my rims, and removed huge pieces of the rim brake surface in just one ride. Did a research, and found bunch of people with the same problem. It was suggested to change it to Koolstops. These are much easier on the rims.

    I had the same problem with the stock pads on my Trek FX. I was doing a deep cleaning after about 8 months of owning the bike and when I looked at the pads they were filled with metal fragments. I think it was due to the rims being new and not being machined to a finer finish. Replaced them, picked KoolStop. Although I don't really see KoolStop as being anything that great. A lot of people here seem to swear by them but personally I think they're just brake pads. No more, no less.

    They are nothing special as far as brake pads go, but unfortunately, everything else is worse. So the fact remains, they are the best widely available pad on the market.
